FREDERIO W. HILLARD, OF TOTTENVILLE, NEW YORK, ASSIGNOR TO THE ELLIOTTdz HATCH BOOK TYPEWRITER COMPANY, OF NEW YORK, N. Y.,

A OORPORATION'OF NEW YORK.

BOOK-TYPE-WRITER TABLE.

SPECIFICATION forming part of Letters Patent No. 726,922, dated May 5,1903.

, Application filed August 31, 1901. Serial No. 74,016. (No model.)

To aZZ whom it may concern.-

Be it known that I, FREDERIC W. HILLARD, a citizen of the United Statesof America, and a residentpf Tottenville, in the county of Richmond,city and State of New York, have invented certain new and usefulImprovements in Book-Type-Writer Tables, of which the following is aspecification.

This invention relates to book-type-writer [0 tables of the gen eralprinciple disclosed in my application, Serial No. 27,040, filed August16, 1900, in which two book-supporting leaves or book-rests areemployed, one for each cover of a book, and which are relatively movableone to the other, the parts being so disposed as that ample room isprovided in the space under the book-rests for the legs of the operator.

The objects of the invention are to provide a book-typewriter table inwhichthe said book-rests are mounted so as to move independently one ofthe other and to self-adjust themselves when loose, according to thethickness of the book, after which they maybe fixed stationary, so thatwriting upon the book may take place.

My invention consists of certain features of constructionand'combi-nations of parts, to be hereinafter particularly described andthen claimed.

In the accompanying drawings, Figure l is a front elevation of abook-type-writer table embodying the present invention, the writingmechanism being indicated in dotted lines. I

Fig. 3 is Fig. 2 is a plan view of the same.

an end view thereof, and Figs. 4, 5, and 6 are detail views showing themeans for adj usting and setting the book-rests in position.

Referring to the drawings, A indicates the 40 table; B, the writingmechanism; B, the baseframe therefor, and O the platen. The platen andthe base-frame are pivoted on a shaft D, which is mounted on smallwheeled guidetrucks cl, the wheels of which travel upon the 5 top of thetable, and the frames of said trucks being each provided with anundercut groove which receives a correspondingly-sectioned guide-rail A,which is fixed to the rear part of the top of the table and extendslongitudinally thereof, so that the platen and all the writing mechanismmay moved lengthwise of' the entire length of the table. A longitudinalguide-rail A is fixed to the front of the top of the table in positionparallel with the guide-rail A, and the platen has at its outer end aguide-roller O, which runs on the said rail A The object of thisconstruction is to enable the writing mechanism to be movedsay to theright-hand end of table'so as to clear the book-rests E E, which move inan opening in the top of'the table.

. Book-rests E E aresupported in parallel position at a suitabledistance apart, preferably by means of upright slides F F, which aresecured to the rear ends of the book-rests EE and are braced byangle-irons or brackets e e. The slides F F are guided in Verticalparallel gnideways atfon the inner surface .of the back of the table, soas not to interfere in the space under the book-rests with the legs ofthe operator.- Each of the slides and the book-rest supported therebyis; subjected .to .a lifting action'bylmeans, preferably, of a helicaltension spring G, hung on a stud g, projecting through a slot f from theback of. the table, and the lower end of which spring carries ascrew-threaded stem G, that passes loosely through a perforated lug g atthe lower end of the slide, and is adjusted longitudinally therein, soas 80 to create more or less tension on the spring, by means of athumbnut 9 that works against the under side of said lug. When thebook-rests are'free to give todownw-ard pressure, a book placed inwriting position thereon will lower them, and when the platen is loweredso that its front guide-roller comes in contact with the front rail Athebook-rest E, over which the platen islowered in the position of partsshown in Fig. 1, will be depressed to the proper level'or plane, whilethe cover and leaves of the other half of the book exert a leverageaction on the other. book-rest E and cause it to seek the proper levelor plane. In these or any other positions in which the book and platenwill cause the book-rests to be automatically moved to the proper levelor plane the book-rests are ordinarily fixed rigidly in position forpermitting the proper functioning of the writing mechanism. Each slide Fis therefore provided with a locking device (shown in Figs. 4, 5, and 6in detail) constructed, preferably, as follows: To the table, at eachside of the space under the book-rests, is pivoted at h a lever H, theinner rear end of which is connected by a link it with an ear 7&2 on theunder side of the book-rest and the forward end of which is providedwith a sleeve i, through which is guided a spring-pressed locking-pint", that is provided at its outer end with a button I, so that thelocking-pin may be retracted to overcome the spring action and towithdraw it from any one of a series of holes j, formed in a plate J,fixed to the table. In permitting the book-rests to self-adj ustthemselves according to the thickness of the superposed parts of thebook to be written in the pins t" are retracted from the holes jreceiving them, and when the required set of the book-rest is obtainedthe pins are released and permitted to engage with the nearest hole.

If a leaf above the book-rest E is to be written upon, the platen andwriting mechanism are shifted thereover, while if a leaf above thebook-rest E is to be written upon they are shifted thereover, and ineither case and when the platen and writing mechanism are to be movedentirely clear of the book at the right-hand end of the table the saidparts are guided on the longitudinal top rails, which extend from oneend to the other of the table.

It is evident thatcertain changes are within the scope and spirit of theinvention-as, for instance, the book-rests and manner of supporting andoperating them may be differently constructed in a case where thewriting mechanism travels on rails in front of and behind the same.

What I claim as new is- 1. In a book-type-writer table, the combinationof two independent slides, suitable actuating-springs suspended fromtheir upper ends and acting, at their lower ends, on the slides, andbook-rests supported by the slides, substantially as described.

2. In a book-type-writer table, the combination, with a book-rest, of astationary guiderail extending along the rear of the table, a truckguided on the said rail, and a platen for the writing mechanism, guidedon said rail, and pivoted to said truck, substantially as described.

3. In a book-type-writer table having vertical guides in the rearthereof, the combination of two independent slides, moving in theguides, book-rests projecting forwardly from and supported by theslides, springs hung at their upper end from the table and having theirlower ends attached to the slides, and an operating-lever provided withlocking devices for fixing the position of the book-rest, substantiallyas described.

4. In a book-type-writer table having vertical guides in the rearthereof, the combination of two independent slotted slides moving in theguides, book-rests projecting forwardly from and supported by theguides, studs projecting from the table through the slots in the slide,springs fastened at their upper ends to the studs and having their lowerends attached to the slides, and levers, one attached to each of theslides, and provided with looking devices for fixing the position of thebookrest, substantially as described.

5. The combination with a book-type-writer table, comprising twoindependently vertically self-adjustable book-rests and guide railssupported independently of the bookrests in the front and rear thereof,of a writing-machine comprising a platen and writing mechanism pivotedto one of said rails and resting on the other, the platen and writingmechanism being movable on the two guiderails, substantially asdescribed.

6. The combination with a book-type-writer table, comprising independentbook-rests, and having stationary guide-rails arranged in front of andbehind the rests of trucks movable on the rear rail, ashaft mounted onthe trucks, and a platen and writing mechanism pivoted on the shaft andadapted to rest on the front rail, substantially as described.

7. The combination with a guiderail, of trucks movable thereon, a shaftcarried by the trucks, and a platen and writing mechanism pivoted on theshaft, substantially as described.
